ASH-SlFTl-IR.

SPECIFICATION forming part of Letters Patent Iva-423,485, dated March 18, 1890.

Application filed November 7,1889. Serial o. 329,495. (No model.)

Maine, have'invented a new and useful Ash- Sifter, tion. v V

Our invention relates to improvements in ash-sitters; and it consistsin' certain novel features hereinafter described and claimed.

In the accompanying drawings, Figure 1 is an end view of our improvedash-sifter, showing-the door open. Fig.2 is a longitudinal section. Fig.3 is a transverse section.

The casing A may be of any desired size,

and is of a semi-cylindrical formation, having a rectangular baseprovided with a central circular opening B, and around the said openingwe provide the depending annular collar or flange C, which is adapted tofit in the upper end of a barrel or other receptacle, as will be readilyunderstood. In one end of the casing, hinged at its lowest point, weprovide the door D, through which the ash-pan or drawer E may be passedinto the casin g. This door D'is held in its raised position by a buttonF, which is pivoted on the end of the casing and is adapted to engageover the upper edge of the door, as shown. of the casing we journal ashaft G, having a crank-arm H at one extremity, by means of which it maybe rotated, and on this shaft within the casing we secure thecylindrical screen or sifter I, as clearly shown. A latch J is providedon the end of the casing, and consists of a fiat plate or bar journaledon the casing and having a notch K in its edge adapted to engage thecrank-handle. The crank-handle will thus be held against movement androtation of the cylinder prevented. Hereinafter-described openings inthe ends of the latter register with the door, wherebythe drawer E maybe passed therethrough when so desired- The cylinder I consists of thecylindrical screening-cloth L and the semi circular plates M, to whichthe edges of the said cloth are secured around one-half of the cylinder.An open space is thus provided in the ends of the cylinder, and in thisspace the of which the following is a specifica Through the ends ash-panor drawer E is placed. This pan or drawer consists of the segmental endplates N and the imperforate bottom and sides 0, secured thereto.

In practice the casing is arranged over a barrel or other receptacle,and the ash-pan or drawer, containing the ashes and cinders, is insertedthrough the doorway inlthe end of the casing into the open portion ofthe cylinder. shaft rotated, soa-s to impart motion to the cylinder, andthe drawer or ash-pan will thus be carried to the top of the cylinderand the contents thereof dumped to the bottom of the same, so that theashes will be forced through the screen into the barrel or receptacle,while the unburned coal will fall back into the ash pan. After the asheshave been sifted the door is opened and the ash-pan removed.

From the foregoing description it will be seen that we have provided anash-sifter which is very simple in its construction and by the use ofwhich the ashes will be easily and rapidly separated from the good'coal. It will be observed that the cylinder is continuous, so that theash-pan or drawer will be held therein without the employment ofindependent securing devices and will be positively carried around bythe cylinder, so as to act on the entire contents of the pan.

The advantages of the device are thought to be obvious, and furtherreference thereto is deemed unnecessary.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

1. In an ash-sifter, the combination of the cylinder composed ofsemicircular end plates and the continuous screen secured to the same,and the ash-pan adapted to rest on the screen, as set forth.

2. In an ash-sifter, the combination, with the cylinder composed ofsolid segmental end plates and a continuous cylindrical screen, of theash-pan composed of a solid bottom of the length of the cylinder andsolid segmental end pieces, which, with said plates, form the circularends of the cylinder, and means for rotating said cylinder,substantially as described. 4 p

3. In an ash-sifter, the open bottomed cas- The door is then closed andthe cranking having an opening atthe side to allow for the side of thecasing, a door for the opening at the side of the casing, and asemicircular ash-pan to be passed through the opening of the casing andadapted to be received Within the cylinder, as set forth.

4. In an ash-Sifter, the combination, with the'screen-cylinder having asegmental opening in its end, a shaft upon which said cylinder isjournaled, and a crank on said shaft,

of the casing having an opening in one end adapted to register with saidopening in the cylinder, a catch on the casing adapted to lock saidcrank when the said openings align, and a drawer, the Whole constructedand operating substantially as described.

In testimony thatwe claim the foregoing as our own we have heretoaffixed our signatures in presence of two Witnesses.
